Your mistake is your presupposition that your government control over private finance is an improvement over your fears of a future serfdom.
The people in power already want to rule forever, democracy hasn't protected you form this.
What I suspect you really want is a limited government without the capability of having so much power it can turn you into a serf

But You don't like the open market alternative.
So you keep trying to make a political solution,
But if your government control is strong enough to control market outcomes all you've done is create a point of control that someone will use to turn you into a permanent serf anyway
